Answer:
6 races
Step-by-step explanation:
If he won 40% of the races he competed in, and he raced 15 times, this means that he won roughly 4/10 races.
4/10= ?/15
cross multiply 4 and 15 = 60
60/10 = 6
He won 6 races
Give brainliest please!
hope this helps :)
Answer:
commutative property of multiplication
Step-by-step explanation:
doesnt matter 2*1 or 1*2 you will get the same answer
All together, 14 plants have been given away. Because, Gregory gave 2 away the first year. The next year, those 2 friends together give away 4 plants. The following year, those 4 friends give away 8 tomato plants. So 2+4+8=14
Answer:
the solution is (4, 1).
Step-by-step explanation:
The goal here is to "solve this system of linear equations." You need to share that along with the equations.
We can begin the solution by substituting 3y + 1 for x in the second equation:
2(3y + 1) + 4y = 12
Performing the multiplication, we get 6y + 2 + 4y = 12, or 10y = 10.
Then y must be 1.
Substituting 1 for y in the first equation, we get x = 3(1) + 1 = 4
Thus, the solution is (4, 1).
Answer:
A pizza parlor uses square prisms for their pizza boxes. Due to the crust rising, the height of their boxes is always 2 inches. Additionally, the volume of the pizza box must be 450 cubic inches to fit their standard-sized pizza. A worker determined that the equation 2×2 = 450 could be used to find the side length, x, of the box needed to reach that volume.
Determine which statement is true about the solutions to the equation.
A.
The solutions are -30 and 30 but only 30 is a reasonable side length.
B.
The solutions are -30 and 30 and both are reasonable side lengths.
C.
The solutions are -15 and 15, but only 15 is a reasonable side length.
D.
The solutions are -15 and 15 and both are reasonable side lengths.
